Weight of 3mm Galvanized Steel Plate
To calculate the weight of a 3mm galvanized steel plate, you need its length (m) and width (m). The formula is as follows:
- Single-piece weight (kg) = Thickness (m) × Width (m) × Length (m) × 7850 kg/m³
- Example: 3mm × 1m × 2m × 7.85 = 47.1 kg.
- This formula excludes the weight of the galvanized coating.

We Supply 3mm Galvanized Steel Plate Types
Utilizing our profiling, cutting, and other processing equipment, we offer 3mm galvanized steel plates including:
- Galvanized Flat Plate: Directly cut from galvanized steel coils, this is the base-grade galvanized steel plate that remains unprofiled and flat.
- Galvanized embossed steel sheets: Directly embossed on galvanized flat sheets to form raised, regularly patterned designs (diamond, round dot, strip, etc.).
- Galvanized floor decking: Formed through precision roll forming into specific closed or open rib profiles, a specialized profiled steel sheet.
- Galvanized highway guardrail panels: Available in W-type (double wave) or triple wave configurations, these panels are secured to highway sides via posts and blocking blocks.
Note: We also supply galvanized corrugated steel sheets, though their maximum thickness is limited to 2.5mm.
